Issue description

Nodes with groups are not displayed in the scene preview panel. If the node with a group is the root node the whole scene isn't displayed.

Steps to reproduce

• create a scene with a node of any type.
• add a group to that node.
• open the scene preview panel.

This is actually the same problem as #600 and has already been fixed in #603.

Ah, saw that one but thought it only talked about the node_paths field. Glad its fixed.

Thanks for the report! Consolidating in #600.
